A packaging head on a barreled drinking water barrel

Abstract

The invention relates to a sealing head on a barreled potable water barrel. According to the sealing head on the barreled potable water barrel, a water barrel opening part of the barreled potable water barrel is provided with an inward concave edge; the sealing head comprises a hard mounting part and a hard water leakage core part, which are fixedly embedded into the water barrel opening part; the hard mounting part comprises an inner barrel and an outward convex edge part; the inner barrel is provided with an expansion mechanism; the expansion mechanism comprises a push rod, a spring, an ejector rod and a soft sealing part; the inner end of the push rod is an inclined push plane which is inclined downward; an outer end of the inclined push plane stretches into an inner hole of the hard mounting part; the spring is located in a mounting through hole; the inner end of the spring is fixedly connected with the outer end of the push rod; the outer end of the spring is fixed onto one end of the ejector rod; the soft sealing part is sealed on an outer wall of the hard mounting part of an outer port of the mounting through hole; the other end of the ejector rod corresponds to the inner surface of the soft sealing part; and the hard water leakage core part is detachably connected into the inner hole of the hard mounting part. The sealing head provided by the invention is sealed by an elastic force and can be prepared from a hard and healthy material; and the sealing head is novel in structure and can be repeatedly recycled.

Description

technical field [0001] The invention relates to a drinking water device, in particular to a packaging head on a bottled drinking water barrel. Background technique [0002] The drinking water barrels installed on the water dispenser have a very single structure for a long time. Generally, during production, the filling water is filled, and then the soft plastic head is sealed, and then it can be sold. When we buy drinking water, we only need to insert the mouth of the drinking water barrel into the smart seat of the water dispenser. The top pressure column of the smart seat will break the blocked plastic sheet, and the drinking water barrel can leak into the water dispenser normally. . But at present, the packaging head on this drinking water bucket has the following deficiencies, which are difficult to overcome: 1. If the plastic material selection of the soft plastic head is not strict enough, many plastics will be easily released when the water dispenser is heated. Toxi...

Problems solved by technology

But at present, the packaging head on this drinking water bucket has the following deficiencies, which are difficult to overcome: 1. If the plastic material selection of the soft plastic head is not strict enough, many plastics will be easily released when the water dispenser is heated. Toxic substances, there are a lot of brand bottled water on the market now, it is difficult to control the quality standards of plastic heads, so there are potential drinking water safety hazards; 2. Due to quality control problems, the sealing pieces in many soft plastic heads and their connections The periphery of the wall is too firm, and the top pressure column cannot break through the blocked plastic sheet at one time, causing the water dispenser to withstand multiple top pressures, and sometimes the smart seat is broken; 3. After the soft plastic head is used once, it cannot Reuse, high cost and waste of materials, is a one-time consumable; 4. When the unfinished bottled water is pulled out, the water will leak straight, so it is troublesome to change the water when it is not finished
